I don't use the DB for performance reasons - i use it because it's easier to handle (well, at least should be ;) ).
The images will change pretty often. If you consider file system vs. database performance, you also have to keep fragmentation in mind. Although modern *nix-filesystems tend to be resistant against fragmentation issues, a _very_ large fluctuation can still cause serious performance loss (as you can see with Gentoo Linux's portage tree).

But as said before - its just easy to handle. You don't have to care about potential security headaches with uploading binary files into your cgi-dir, permissions etc. Just 'insert' and 'select', and there you (should) go. And i still have to get the content-type, either by extracting it from the image (bad idea) or by getting it from the Database.

Some more Information about my problem: System is a current Gentoo-Linux with perl 5.8.6, mysql-4.1.14, DBD::Mysql 2.9007, DBI 1.46. When using the console-client 'mysql', everything works as expected. Same with phpMyAdmin.
The following code also works: 

 my $sql = "select type from bilder where id =?";
    my $sth = $dbh->prepare($sql);
    $sth->execute( $q->param('id') );
    my $error = 0;
    my $type = $sth->fetchrow || ( $error = 1 );
    $sql = "select data from bilder where id =?";
    $sth = $dbh->prepare($sql);
    $sth->execute( $q->param('id') );
    my $data = $sth->fetchrow();
    binmode(STDOUT);
